Is it normal that I can't stick to one thing to do at a time?

I've been having the same problem lately but I think it's the meds I'm on I wake up after about 3 hours get out of bed tell myself what I need to do in the next hour like cook breakfast for my boyfriend then clean the kitchen and as I'm telling myself this I'm also thinking I wonder if I got more farmville gifts then new thought well I have about 3 hours before I have to cook lunch and get on Facebook then coupons.com and it keeps branching off until I have about 30 minutes to get lunch done clean the kitchen and do the laundry I'm constantly back and forth between my room the kitchen and my computer it's been driving me nuts I have a mountain of unfolded clean laundry an art project and home improvement project now and I keep telling myself I'm gonna finish everything today but it never gets finished because I start then drift into procrastination nation and it gets put off except for cooking and the dishes these are mandatory and I have to pry myself away from the screen
